Chapter , Problem 3.11(choose chapter or problem)
For the transformer in 3.10, the open-circuit test with 11.5 kV applied results in a power input of 65 kW and a current of 30 A. Compute the values for Gc and Bm in siemens referred to the high- voltage winding. Compute the eciency of the transformer for a load of 10 MW at 0.8 PF lagging at rated voltage.
